T0 all ywhom i?? may conceTf/z:

Be 1t known that L H Nm P., KRAFT, a men of the Unte States of mema, fe-

a de'ato, but it s also held conneched with v the valve shell before the miv@ is puced in usfs.

prmng n momma be che spun ahnung such jmc, so thai pu in use siding in Rn'gewood, in the county of Bei gen and. Stam of New QQL'SW7 havenvented Certain new und uexetfu mprovemen's .in 5z'c`\2.l\es, Gf which the fC-lcwingg is specification.

This nppicainn is a dvsnn of my appli- 5w valve is; f SMB has me naive the pas? the drmvings, which Show severa mof catons he im'enton,

Figui@ is l dianwtrcl Valve showing' @ne heree;

2 is View of cap, sacinternal scr`ew-thread adapted to 'screw on the nipple'of the valve shell When in its normal position, whereby to malle a leak tight closure vfor `the valve shell. The internal `stru-'stare of the Cap 'is notsliovvn, since this 'ryzonstruotionpsiwell known; Such valve 'caps ere'-each,-1noreover' usuallydprovided With`= `efprojeeiijlon kat its outerf end which is ,designed to;r4 enter the velve'shell and unscrew the plug Gg'by, engagement with the projecting portion-S of the plug.

In the' ycenstruetion ,illustrated in Figs. l and 2' the metal at the upper'end of the projeotionof theeap is forced together at T endU-betweenthe projections V and W, thus forming an 'abutment which engages the' valve pin, as shovv'n in Fig. l. The projections V and W are still useful to unscrevv the plug G, as is common, While being. sufiiciently sprung apart to engage the valve casing by friction.

In Fig. 3 theupper end of the cap R is elongated, as shown at X, and is provided with the same inwardly ressed 'portions T (and U),'as are shown in Figs. l and 2. The upper end of the cap is also formed with a, stop Y which serves to prevent the'v esgape of a screw coupling Z. The latter 1sv des'gned to engage4 the valve casing and press the oep downwardl depressed. When it is esired to use the cap to unscrew the plug G the coupling Z is slid upwardly and out of the'way.

Vhen the valves arerassembled, ready for shipping, the eap R is reversed and engaged with the valve shell, the friction kor coupling holding the cap in place. When the valve is applied to the tube and is ready for use the cap Will, of course, be reversed and thereafter perform the normal funetion of a cap.

' While I have shown and described several forms of the invention, it Will be understood that I do not Wish to be limited thereto, since various changes can be made .screw driver l depress a 'valvepin 'when so inserted, and
